I think Spurlock sells a "bag of beans", that can be placed on top of the dampers to weight them down. Personally I have never used anything to weigh them down. If any pressure is needed to make sure a damper fits right, I just use a finger. I believe the weight of the damper lever should be enough to properly seat a damper. But, as Joe mentioned, you have to make sure the strings are level. Just my?4 cents worth.

I used a couple of pieces of pvc pipe with a small block of wood on top to put on the new dampers with the intention of helping the new felt conform to the string. However, a couple of weeks ago a well-respected tech said that other techs and he shared the opinion that this practice caused problems for them, actually deforming the felt due to the extra weight. I feel like I am spending more time than I should to get a new set of dampers working effeciently so I tried this. At least on the piano I just finished, I had better results without the seasoning weight. What are your experiences regarding this practice?
